C编译器标识未知

Question

我想编译一个C程序.我跑的时候cmake

   build]$ cmake ../
    -- The C compiler identification is unknown
    -- Check for working C compiler: /usr/bin/cc
    -- Check for working C compiler: /usr/bin/cc -- broken
    CMake Error at /usr/share/cmake-3.0/Modules/CMakeTestCCompiler.cmake:61 (message):
      The C compiler "/usr/bin/cc" is not able to compile a simple test program.

它失败并带有以下输出:

为什么会出现这种错误？我该如何解决？

Answer 1

为什么会出现这个错误？

根据此错误消息:

/usr/bin/cc -o CMakeFiles/cmTryCompileExec3431547622.dir/testCCompiler.c.o -c /home/vahid/dev/Indexer/build/CMakeFiles/CMakeTmp/testCCompiler.c

/usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.0/cc1: error while loading shared libraries: libisl.so.13: cannot open shared object file: No such file or directory

看起来你的编译器不起作用.

我怎么能解决它？

重新安装工具链应该是解决它的最简单方法.

如何做到这一点取决于您的操作系统,如果您使用像Debian这样的Linux发行版,您可以使用类似apt-get install build-essential安装它的东西; 如果你使用Fedora或CentOS,你可以使用yum group install c-development.
